I wasn't able to find the quote I was looking for, but I remember reading somewhere that even if you made a theoretical computer out of all the matter on earth it would take more time than the universe has existed to crack basic encryption with a brute force method. Here is a similar description on wikipedia.
The amount of time required to break a 128-bit key is also daunting. Each of the 2^128 (340,282,366,920,938,463,463,374,607,431,768,211,456) possibilities must be checked. A device that could check a billion billion keys (10^18) per second would still require about 10^13 years to exhaust the key space. This is a thousand times longer than the age of the universe, which is about 13,000,000,000 (1.3×10^10) years.
Even using only AES128, brute force is impossible. If you use AES256, then it will take the square of that time to crack.
Be Original: Avoid being redundant and just repeating what has already been said. Smirk. Yes, being moderated as "redundant" is worth "-1" to your post and your karma. Especially to be avoided are the "what he said" and "me too" posts.
Take note of the first quoted comment to avoid. I understand that you feel like his description matches your experience, but you haven't added anything to the conversation. Your comment was certainly not harmful, but it wasn't helpful. Hence the Redundant moderation. All you need to do is say What he said, and then expand on your situation and you have a recipe for an insightful post. Also if you really want to make sure you get moderated well, add in a "I know i'll get modded down for this but...". Moderators love that shit.
IANAS, but the idea of a space elevator is that not only will the "cable" be held up by the centrifugal force of spinning around the earth, but Space elevators do not exist because we haven't discovered/invented a material which can withstand the tremendous force of spinning in a circle. If a space elevator were to fail, I think the worst scenario would be the elevator goes drifting out into space.
Even if the cable were to fall to the earth, the reason re-entry creates so much friction is that spacecraft are moving at tremendous orbital velocities. A space elevator would only have the angular velocity of the earth, so locally it would have no angular velocity. Unless it was sent whipping around the earth by some external force, it would simply fall down.
It has always baffled me that a website that seems to have such a good supply of technical knowledge could be so incompetent at implementing a pay-wall.
Does this serve as an indirect or otherwise passive-aggressive push for network neutrality? I suspect it might be.
It sounds to me like a push completely against net-neutrality. The websites that are served up faster get a higher rank. The websites that are throttled get a lower rank. Net neutrality isn't about how website owners filter their bandwidth for their visitors; they've always been free to do what they want. Net neutrality is about the ISPs and other backbone entities of the internet throttling traffic. If there was an ISP between google and two webpages it could direcly influence their ranks by throttling the site it wants knocked down and prioritizing the site it wants to give a higher rank to.
Half the people I heard from said that if they scroll all the way to the bottom they can read the answers for free, and the other half say this doesn't work. This confused me for the longest time until I finally figured out the answer.
Expertsexchange allows you to scroll down to the bottom to get a free answer the first time you visit their page, then gives your browser a cookie saying that you have gotten your free answer, and won't show you any more. So if you want to ensure that you can always scroll to the bottom, you simply have to block cookies from them and you are good to go.
If this happens, Leiss worries that there will be one more genetic tweak: some of these elites will make their offspring genetically incompatible with others. Differences between classes will be transformed into differences between species.
In a scenario like this, there is only one winner: The doctors
Scenario 1) I play starcraft for a year, I am done playing, so I sell to my friend directly. I give him my CD-KEY and ownership is transferred. Since as you mentioned I could keep it installed, this requires trust.
Scenario 2) I play game X for Xbox 360 for a year, I am done playing, so I sell to my friend directly. I give him the codes but he CANNOT use the DLC that came with the original purchase. The content of the game is tied to the first purchase.
Even if two people installed with the same CD-KEY there would not be a problem unless they tried to log on to battle.net at the same time.
Is this any different from the use of unique 'CD-Keys' that are required for online play (e.g. for Blizzard games since 1997 or earlier)?
Yes, the CD Keys for Blizzard Games travel with the game. Only one can be active online at any time, but you are perfectly able to uninstall the game and sell it to someone else. DLC is locked in.
Ideally, the system should also have a "relinquish" command. If I buy a game, get the DLC, then decide to sell the game, I should be able to "deactivate" that code (assuming it's tied to my gamer id or something? Who knows.) Then the next person can download the dlc for free. GameStop might even require people to log in and deactivate their codes before trading in a game, so as not to screw over the next user.
The entire reason the DLC system is being used is so that the content does NOT travel with the game, reducing the resale value.

So..... Dear George, your library fees are now -$32768.00
It turns out if you wait long enough you no longer owe money on them, but the library will pay you to bring them back!
Already posted, but good post.
Pirating games only supports DRM, and even better than just not playing the game is supporting games which do not use DRM.
This DRM was designed, developed and produced by a multicultural team of various religious faiths and beliefs.
I have altered the deal. Pray I don't alter it further.

Baby it don't matter, they're all beautiful on the inside.
Cool people from around the world to talk with, and you never know who you're going to talk to next. Kind of like fishing
Yet they all just seem to be guys masturbating...

Well since the ISS spends most of its time in free fall, it is a zero-g environment.
Really, there weren't that many choices. Lucid Lemur is not nearly as exciting.
